MEASURING AND REGISTERING FAUCE'I.

Specification of Letters Patent. Patented; Dia 1, 1910.

Application filed April 29, 1909. Serial No. 492,947.

To all whom "it may concern:

Be it known that I, IVILLIAM JAMES Mo- MILLAN, a citizen of the UnitedStates, residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented certain new and useful Improvements inMeasuring and Registering Faucets; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in measuring and registeringfaucets.

The object of the invention is to provide a faucet of this characterhaving a valve plug in the form of a receptacle adapted to contain agiven amount of liquid, and having means whereby each discharge 0 thecontents of the receptacle is registered, and means whereby a totalrecord of the amount of liquid drawn is also recorded.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claim.

In the accompanying is a side view of a measuring and registering faucetconstructed in accordance with the invention; Fig. 2 is a horizontalsectional View on the line 22 of Fig. 1; Fig. 3 is a central verticalsection on the line 33 of Fig. 2; Fig. 4L- is a horizontal section onthe line le-4 of Fig. 3; showing the total registering disk and itsoperating pawl in plan view; Fig. 5 is a similar view on the line 5-5 ofFig. 3, showing in plan view the gear and pawl for actuating the primaryregistering disk; Fig. 6 is a vertical sectional view, taken at rightangles to Fig. 3; Fig. 7 is a detail plan view of the notched disksupporting plate; Fig. 8 is a similar view of the notched pawl holdingplate of the total registering disk.

Referring more particularly to the drawings, 1 denotes the faucet whichconsists of a tubular body portion 2, from one side of which, adjacentto its upper end, projects a threaded attaching shank 3, by means ofwhich the faucet may be secured to a barrel or cask. On the oppositeside of the body 2, adjacent to its lower end is arranged a dischargespout 4. In thus arranging the shank 3 and the spout 1, it will beunderstood that the liquid is admitted to the body portion of the faucetnear its upper end and is discharged therefrom near its lower end.Mounted to turn in the body portion 2 of the faucet is a hollow plug 5,the upper end of which is closed by an integrally formed upwardlyprojecting valve stem 6, while the lower end is closed by a removablestopper 7 having an annular flange 8 which engages the lower edge of thebody portion 2 and holds the plug in operative position therein. Theplug 5 may be of any suitable size and is intended as a unit of measurewhereby the amount of liquid drawn each time the faucet is turned on isknown. In one side of the plug 5, adjacent to its upper end, is an inletport 9 which, when the plug is turned to proper position, willcommunicate with the tubular shank 3 thereby permitting a liquid fromthe container to ow into the hollow plug. In the lower portion of theplug in a plane at right angles to the port 9 is arranged a dischargeport 10 which, when the plug is turned in the proper direction willcommunicate with the discharge spout 4 and thus permit the liquidcontained in the plug to pass out. By arranging the ports 9 and 10 asdescribed, one of the same will be in closed position when the other isin open position, or in other words, when the inlet port 9 is incommunication with the spout 4, the discharge port 10 will be closed bythe adjacent walls of the body portion 2 and when the discharge port 10is in line with the spout 1, the inlet port will be out of line with theshank and closedby the adjacent wall of the body portion 2.

In connection with the faucet, I employ a registering mechanismconsisting of a supthe upper end of the plug 5. The plate 11 is providedwith a centrally disposed aperture, surrounded by an upwardly projectingexteriorly threaded nipple 12 into which the valve stem 6 projects. Theplate 11 is also provided with a downwardly projecting annular flange 13which loosely engages the upper end of the valve plug and fits over thereduced upper end of the body portion 2 of the valve. The flange 13 isprovided in its lower edge on one side with a notch 1 1 which engages astop pin 15 arranged in the shoulder formed by the upper reduced portionof the body of the valve, thereby drawings, Flgure 1 locking the plateagainst movement on the upper end of the body portion. The re disk by aspring 30. The plate 27 is produced upper end of the body portion 2 iscut-away or recessed on one side and the flange 13 is provided with acorresponding slot 16, the purpose of which will hereinafter appear.

On the flange 13 of the plate 11 is mounted to turn a case supportingplate 17 having on its upper side, ad acent to its outer edge, upwardlyprojecting annular flanges 18 and 19 which are spaced apart to form anannular groove or channel to receive the lower end of a case 20 which isprovided to inclose the registering mechanism, said case 20 beingpreferably formed of glass. On the upper side of the plate 17 betweenthe inner flange 1S and the adjacent edge of the plate 11 which restsupon the plate 1? is a pivoted pawl 21 which is held in engagement withthe edge of the plate 11 by a spring 22. in the edge of the plate 11 isformed a notch 23, the purpose of which will be hereinafter described.

Loosely mounted on the nipple 12 and resting on the supporting plate 11is a combined gear and primary registering disk 24, the upper portion ofwhich projects be yond the toothed edge of the lower or gear portion andon the periphery of said projecting edge is arrai'iged a series ofindicating notches or marks 26. hen the registering disk 24 is inposition on the nipple 12 and supporting plate 11, the teeth of the gearportion 25 will be in position to be engaged by the pawl 21, each timethe same is brought opposite to the notch 23 the edge of the plate 11,for the purpose turning the registering disk the distance or one tootheach time the valved plug is turned to discharge the liquid therefrom.The notch 23 is arranged in the plate 11 in such position that the pawlwill be brought opposite the notch about or just before the time thedischarge port in the plug is brought OPlJOSltQ to the spout 1n thefaucet,

so that before the turning operation of the plug is entirely completed,the pawl will enter the notch 23 and thus engage the gear portion 25 ofthe recording disk and move said disk to the distance of one tooth, thusindicating that one more plug full of liquid has been discharged fromthe container. lVhen the pawl 21 is not in engagement with the notch,the edge of the plate 11 holds the pawl out of engagement with the gearportion of the recording disk.

Screwed onto the threaded upper portion of the nipple l2 and engagingthe upper side of the primary registering disk 241; is a pawl holdingplate 27 having in its edge a notch 28, the purpose of which will behereinafter dcscribec. On the upper side of the primary recording disk,adjacent to its outer edge is a pawl 29, said pawl being held inengagement with the edge of the vided with a central upwardly projectingannular flange and on said plate and f flange is loosely mounted a totalrecording disk 32, said disk having on its outer edge a series ofratchet teeth which are rdapted to be engaged by the pawl 29 when thelatter is brought opposite to the notch in the holding plate 27, so thatwhen the primary registering disk has made a complete revolution and thepawl 29 has been carried entirely around the edge of the plate 27, thespring 30 will force the pawl into the notch 28 and into engagement withthe ratchet teeth on the edge of the total registering disk 32 wherebythe pawl will turn the disk to the distance of one tooth before beingagain forcedv out of the notch and held out of engagement with the teethon the disk by the edge of the holding plate 27. ()n the unper side ofthe total recording disk. adjacent to its outer edge, is arranged aseries of graduations which indicate the number of revolutions made bythe primary recording disk thus indicating the quantity of liquid drawnfrom the container through the measuring mechanism of the faucethereinbefore described.

Screwed onto the upper end of the nipple 12 is a retaining plate 33having on its outer edge a downwardly projecting flange Bl which engagesthe upper edge of the priniary recording disk, as shown. The plate 33 isprovided with segmental openings 35, through which the indicating markson the total recording disk may be observed through the glass protectingcase.

On the flanged outer edge of the retaining plate is formed a springdetent 36 which bears against the marked or notched edge of the primaryregistering disk and retards the movement of the same, thus preventingthe disk from being casually revolved or turned to a greater distancethan the space of one tooth 011 the gear portion thereof. Secured to theunderside of the re taining plate is a retarding spring or detent 37which bears upon the upper side of the total recording disk and servesto prevent said disk from being casually rotated or turned to a distancegreater than the space of one tooth.

The valved plug a and the case supporting plate 1'? which carries thepawl 21 are simultaneously moved to open and close the faucet by meansof a laterally projecting stem or handle 38 having a reduced inner endwhich is inserted through an aperture in the downwardly projectingllange of the plate 17 and into a transversely disposed passage formedin the upper end of the valve plug. The reduced end of the stem alsopasses through the slotted portion of of the supporting plate 11 andportion of the reduced the flange 13 through the notched ill) upper endof the faucet body so that in the movement of the handle, saidsupporting plate 11 will not be turned. The opposite ends of the notchin the upper portion of the faucet body, is engaged by the stem orhandle 38 in its movement to open or close the plug and thus limits themovement of the valve plug and plate 11. Between the flange of the pawlholding plate 27 and the lower side of the retaining plate 33, isarranged a spacing ring 40 which prevents the flange 3% on the retainingplate from being forced into too tight engagement with the upper side ofthe primary recording disk and thus interfering with the movement of thelatter.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claim.

Having thus described my invention, what I claim is:

A registering mechanism for faucets having hollow plugs comprising aprimary registering mechanism including a combined registering disk andoperating gear, a pawl operated by the movement of the plug of thefaucet, a plate adapted to normally hold said pawl out of engagementwith the gear of said primary registering disk, said plate having formedtherein a notch to permit the pawl to engage said gear and move the sameand the registering disk one notch at each movement of the valve, atotal registering mechanism operated by said primary recordingmechanism, said total mechanism comprising a registering disk having onits outer edge a series of ratchet teeth, a pawl carried by said primaryregistering disk, a pawl holding plate adapted to normally hold saidpawl out of engagement with the teeth of said total registering disk,said plate having formed therein a notch whereby the pawl is permittedto engage said ratchet teeth and operate said total registering disk thedistance of one tooth at each complete revolution of the primaryregistering disk, means to prevent the casual operating of saidregistering disk, and a handle operatively engaged with said valve plugand primary registering mechanism whereby thesame are simultaneouslyoperated.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
